LOUIS KLOW, OF CHICAGO, ILLINOIS.

FEED TROUGH.

Application filed March 1, 1924.

To all whom it may concern:

Be it known that I, Lorns Know, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Feed Troughs, of which the following is a specification, reference being had to the accompanying draw- 111g.

This invention relates to improvements in feed troughs, and particularly to troughs that are designed to be used for holding feed for hogs. It is the object of the invention to provide a construction that will be strong and durable; that can be nested one within another to enable a large number of them to occupy the minimum amount of space for shipping or storing purposes, and that can be readily and easily secured by the user to a fixed support, which object I accomplish as shown in the drawing and hereinafter particularly described. That which I believe to be new will be pointed out in the claims.

In the drawing, Fig. 1 is a perspective view of a feed trough embodying the invention;

Fig. 2 is a vertical longitudinal section through the trough;

Fig. 3 is a vertical cross-section taken at the line 3-3 of Fig. 2, a portion of the device being broken away; and

Fig. 4 is a horizontal section taken at the line 4. 4: of Fig. 2.

Referring to the several figures of the drawing, indicates the bottom and 11, 11 the two side walls of the trough which, as shown, are formed from a single piece of sheet-metal. The two side walls are inclined upwardly and outwardly from the bottom 10, and the marginal portions of the sheet from which these parts are formed are turned outward to form flanges that are approximately horizontalsaid flanges being each indicated by 12. The end walls of the trough are indicated by 13, 13, and, like the side walls, are inclined upwardly and outwardly. The side walls are connected to the end walls and bottom by so bending their adjacent marginal portions as to form hook-shaped strips that interlock one with another as indicated at 14, thus forming a lock seam .or joint for connecting these parts t t twhi en a d interlocked Serial No. 696,254.

marginal portions are tightly pressed together, will, without the use of solder at such joints, provide a receptacle that will hold liquid or semi-liquid food without liability of leakage therefrom.

In connection with each end wall. 13 is provided a supporting member 15, which, as here shown, is formed of the same piece of sheet-metal as the end wallsuch piece of material being bent upon itself along the line 16 so as to form the supporting'member 15 in the shape of a substantially vertical rectangular wall that extends down as far as the bottom wall 10. Inasmuch as such members 15 are substantially as wide as the greatest width of the trough they are well adapted to resist any tendency of overturning of the trough by downward pressure that might be applied to the upper edge of either side wall by an animal that was feeding from the trough, or otherwise, but as it is desirable that the trough be secured in place the lower marginal portions of the members 15 are turned to form flanges 16 in which are formed holes 17 for the passage of screws or nails that hold the device as a whole firmly to a suitable base.

Owing to the rough usage to which devices of this character are subjected, it is desirableand particularly so when the trough is of considerable lengththat the side walls 11, 11 be braced or held together intermediate of their ends, but it is also necessary, in order that the nesting of the troughs may be accomplished for shipping or storage purposes, that any bracing device that is employed be readily movable from across the trough. As shown, I provide a bracing member in the form of a strong stilt metal bar 18 that is permanently but pivotally connected by a pivot pin or rivet 19 that passes through an end portion of such bar and through the flange 12 of one of the side walls 11. The other end of the bar overlies the flange 12 of the other side wall and is adapted to be removably secured thereto by a bolt 20 and nut 21.' The bar 18 not only serves as a brace, but serves as a desirable means for holding the heads of two adjacent animals apart when feeding from the trough at the same time. IVhen a number of the troughs are to be nested for shipping or storage the bars of the several troughs are each to released. from i l- 9 flanges to which they are secured by their bolts and then can be swung on their respective pivots 19, as shown in dotted lines in Fig. 1, so as to he ever and upon the other flanges 12.

From the description given it will be evident that a trough embodying my improve ments can be economically constructed and can, in connection with other like troughs, be economically shipped or stored. Also, it will be evident that by reason of its'construction it is deliverable to the user in. condition to be very quickly set up in position for use, as all that is required to be done'is to fasten it in place by the use of screws or nails passed through the flanges at the lower margins of the supports 15, and the bolting of the free end of the bar 18 to one of the flanges 12.

What I claim as my invention and desire to secure by Letters Patent, is

1. A metal'feed trough comprising a sheet bent upon itself to form a bottom and two outwardly and upwardly inclined side walls, and two other sheets tightly secured to the end margins of the side walls and bottom, and each bent upon itself to form an end wall and a downwardly-extending supporting member.

2. A metal feed trough comprising a sheet bent upon itself to form a bottom and two outwardly and upwardly inclined side walls, and two other sheets tightly secured to the end margins of the side walls and bottom, and eachbent upon itself to form an upwardly and outwardly inclined end wall and a downwardlyextending supporting member.

3. A metal feed trough comprising a sheet bent upon itself to form a bottom and two outwardly and upwardly inclined side walls, and two other sheets tightly secured to the end margins of the side walls and bottom, and each bent upon itself to form an upwardly and outwardly inclined end wall and a downwardly-extending supporting member, said supporting member being approximately as wide as the greatest width of the trough.

4. A metal feed trough comprising a sheet bent upon itself to form a bottom and two outwardly and upwardly inclined side walls, and two other sheets each bent upon itself to form an upwardly and outwardly inclined end wall and a downwardly-extending supporting member, the end walls being cured to the end margins of the side walls and the bottom by tin-interlocking of the marginal portions of said several parts.

5. A sheet-metal trough comprising in combination a bottom, two side walls inclining upwardly and outwardly from the bottom, two end walls also upwardly and outwardly inclined from the bottom, the end walls being formed separately from the side walls and having their end margins connected with the end margins of the side walls by interlocking folds and a supporting member extending downwardly from the upper part of each end wall and spaced from such end wall.
